Does scanadf do anything for you that scanimage can't? scanadf is a spin-off of scanimage but scanimage had some improvements after that. So there may be some differences. > For instance, when using my fujitsu fi-4120c, "scanadf --help" shows that > there is a "--paper_size" option available. Actually, it needs to be > entered as "paper_size". I think that's a bug in the fujitsu backend. The SANE standard says: "The option name must consist of lower-case ASCII letters (a--z), digits (0--9), or the dash character (-) only." So the underscaore "_" is not allowed. > Also, there is no "--threshold" option listed on > the help screen, but it can be entered and it does appear to work > correctly. There is an option called "threshold_curve" in the current fujitsu backend. The same comment about the "_" applies. However, I'm not sure if this does influence the handling of scanimage/scanadf. > There are other apparent inconsistencies I've run across using > scanimage, but I don't remember them now. When you come across them again, please show them to us. Bye, Henning
